SPLIT BUSH-BEARING FOR LlFTlNG-RODS.

SPECIFICATION forming part of Letters Patent No. 639,028, dated December 12, 1899.

Application filed March 21, 1899. Serial No. 710 000. (N model.)

To prevent one part be removed and cleansed while the machine from slipping upon the other, we form a lugg is in operation, which will allow of some on one of the meeting edges, and at a diametmovement from an absolute vertical position rically opposite point on the other edge we 40 in order that the bearings may adjust themform a corresponding recess h, and we make selves in alinement with the movement of one part the exact counterpart of the other the rod and in which one split part may be for the sake of economy of construction and the exact counterpart of the other, so that to facilitate the selection and assemblage of the ends of economy may be secured, and in the parts.

The ends of the bearing for the purposes mentioned composed screws preferably do not extend to the bottom 50 of two parts formed as though a complete cylin* of the said recesses. I

The outer surface or periphery of the bearin g is appreciably crownedin form, or, in other Words, is made tapering from or about the center to the ends, so that the bearing when in place maybe allowed to rock or move from a vertical to an inclined position in order to aline itself exactly to the line of movement of the lifting-rod and so avoid any binding of the latter in the bearing. It will be noted in this connection that the bearing has practically a line contact with the walls of the opening in the rail, and hence is readily self-adjusting.

76 designates nicks formed in the outer surface of the bearing near the end for the reception of the end of a screw-driver or other tool or thing to drive or lift the hearing out of place in the rails f.

It will be seen that with a bearing of the construction described all of the advantageous functions hereinbefore ascribed to it will be readily accomplished to the ends of saving time and securing an easier and steadier operation of the lifting-rods besides providing against undue wear of the bearings.

It is to be noted that the bearing constructed as described is capable of insertion and removal from above or below the rail, whichever may be most convenient. Furthermore, the employment of two screws, one engaging each member of the bearing, insures their retention in proper position without relying upon the interlocking of the sections. Furthermore, the interlocking construction or formation hereinbefore specifically described is such as to insure proper endwise assemblage of the two parts of the bearing, it being an object to render these parts non-reversible end for end with respect to each other, since the exterior contour of the bearing differs on opposite sides of a transverse median line thereof.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be madeor all of the modes of its use, it is declared that what is claimed is l. The combination, with the longitudinally-movable rod or shaft and the rail or support having an opening of uniform diameter for the passage of said shaft therethrough; of a split bush-bearing for the rod tapered toward each end and insertible in the opening of the rail from either side of the latter, said bearing being composed of substantially semicylindrical sections whose abutting edges have interlocking formations preventing relative longitudinal movement of the sections; together with means for holding the bearing in place, substantially as described.

2. The combination with the longitudinally-movable rod or shaft and the rail or support apertured for the passage of said shaft therethrough; of a split bush-bearing composed of substantially semicy-lindrical sections fitting around the shaft or rod in line contact with the walls of the aperture in the rail and having exterior oppositely-located recesses or sockets; together with screws entered through the rail and occupying said recesses or sockets respectively.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 23d day of February, A. D. 1899.
